To all whom it may concern .1 j v a, Be it known that we, EIJMER LEwIsLEE and ,EUGENI; T. DE Wrr'r, citizensof the United States, residing inthe city and county of Denver ,and State of Colorado. have'inventedcertain new'and useful Improvements in Car-Doors, of which the followingis a specification. V

This invention relates to an improvement in car doors, and has t'o domorepa'rticularly with the type of cardoor' set forth in our jointapplication filed January 5,-1914, Se

the car. At the upper right-hand corner of volving some of the featuresof that inven{ tion, although simplified in form, and also I certainnovel features of construction and combinations of parts which will beherein after more fully described and pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of a portionof a car showing our improved door closed; Fig. 2 is an enlarged detailin section through a. portion of the car and the upper right-hand cornerof the door; Fig. 3 is a side view and plan of the wedge located on thedoor; Fig. 4 is a side view in plan of the wedge on the car bodyadjacent to the rear edge of the. door; Fig. 5 is an enlarged transversesection through the lower portion of the car showing the lower edge ofthe door; Fig. 6, is a side elevation, plan and end elevation of thewedge secured to the top of the door for forcing the latter down whenclosed; Fig. 7 is a plan in side elevation of the top rail, parts beingbroken out at the center;

' Fig. 8 is an enlarged side elevation of one of the lower brackets;Fig. 9 is an enlarged edge view of the forward edge of the door andshowing the car body in section with the latch applied thereto; Fig. 10is an enlarged side view of the door-opener; Fig. 11 is a plan view ofthe hasp; Fig. 12 is a plan and side elevation of the catch at the rearedge of the door; Fig. 13 is a side elevation in plan of the door-stopat the rear end; Fig. 14 shows the catch-strap in two differentpositions at right-angles; and Fig. 15 is a fragmentary horizontalsectional view through the lower edge of the door, showing the beveledcorners at diagonally opposite points. V

The numeral 1 indicates the car, portions only of which are shown; and2, is the door, mounted on rollers 3, 3, at the bottom, which are heldin brackets 4, 4, secured to the side and opened. To'this end theguard-track'5 E S; A -NT; OF 0 1 of the car beneath thevdoor, the upper,edge 7 door tight to the car body. at all fourcorners when closed, andfor forcing it out" ward therefrom as the door is unfastened is providedwith the incline ,6 at the for;

the door strikes when closed, whereby it is forced inward securelyagainst the body of the door a bracket 8, shown in Fig. 6, is secured.This has an incline 9 thereon, and a against which the upper left-handcorner or ward as well as inward at the rear edge. At

*the lower left-hand corner, a guard 12 having an incline 18 similar toincline 6 on the guard-track 5 is secured,-the inner end thereof beingheld by the adjacent bracket 4, and the corner of the car-doorby'striking the inner face of the incline 13 is forced inwardly. At theright-hand corner, the bracket 14 corresponding to the several brackets4 is secured, but thisbracket 14 is extended up wardly in theform of anarm 15, as shown enlarged in Fig. 5, the free end of which is in thepath. of a wedge16 (see Fig. 3) secured on the corner of the door inposition to crowd beneath the upper free end of the arm 15 when the dooris closed to hold the lower right-hand corner securely against the sideof the car. 7

A wedge 17 (see FigJ4) is secured to the side of the car immediatelyadjacent to the right-hand lower corner of the door in posi- 131011110be engaged by the doorthe moment it is forced open to throw the loweredge of the door slightly outward away from the car body, sothat itwillnot scrape against the latter in opening and closing.

door when open and receive I the springcatch 19 secured to theright-hand lower corner of the door by screws or bolts 20 and straps 21,(see Fig. 14). a The door when closed is locked by means of the hasp'22, one end of which receivesthe staple 23 where it is held by a pin,padlock or other fastening means 24. This hasp is pivotally secured onthe cam starting lever 25, which lever is fulcrumed at 26 on the r v Astop 18 is located in position to stop the car and has a cam 27 inposition to engage the edge of the door when the lever is swungoutwardly or to the left after having unfastened the hasp 22. This leveris provided to start the door as it is apt to stick, owing to the tightcontact created by the wedges between the door and car-body.

From the foregoing it will be seen that we have provided a door whichcloses practically air and dust-tight against the car, thus preventingvibration and play, and also the loss of any of the contents of the car.

We claim The combination with a car body, of a door having the forwardedge beveled on its exterior surface and the rear edge beveled on theinterior surface, rollers on which the door travels, brackets forsupporting the rollers on the car body, a guard-track and guard havinginclines for forcing one edge of the car door inwardly against the wallof the car body, the opposite edge of the door can in wed es at eachcorner means on the guard-track engaging one of the wedges for forcingthe door inwardly, an extension on one of the roller brackets engagingthe other wedge for forcing the door inwardly, and a wedge connected tothe car body engaged by 'thebeveled surface on the rear edge of the doorfor causing the door to be forced outwardly when the door is being Qp d-1 te t mo w r f We f ix. 0111' s n tures, in the presence of twowitnesses.
